Lithium-ion batteries (LIBs) have been widely used in portable devices and electrical vehicles because of their high energy density. However, the increasing price of lithium resources implies that LIB is not a suitable candidate for large-scale energy storage systems. Therefore, sodium-ion batterie (NIBs) have aroused attention as a promising candidate for large-scale energy storage systems owing to the abundance and low cost of sodium resources. In our study, several advanced metal oxides were conducted as electrode materials for LIBs and NIBs.

The second topic will introduce microbial fuel cell (MFC) which has deeply attracted scientists’ attention as a new sustainable energy device in the past several years. MFCs can transform chemical energy into bioelectricity by utilizing active microorganisms as biocatalyst in the anode compartment. In our study, biowaste-derived activated carbon was fabricated with different activating agent ratios.
